Answer
$X_{max}=9,X_{min}=3,Y_{max}=10,Y_{min}=2,X_{scl}=1,Y_{scl}=2.$
Work Step by Step
As we can see on the figure: $X_{max}=9,X_{min}=3,Y_{max}=10,Y_{min}=2.$
There are $6$ sections on the "x-axis", hence $X_{scl}=\frac{X_{max}-X_{min}}{6}=\frac{9-3}{6}=1.$
There are $4$ sections on the "y-axis", hence $Y_{scl}=\frac{Y_{max}-Y_{min}}{4}=\frac{10-2}{4}=2.$
Thus $X_{max}=9,X_{min}=3,Y_{max}=10,Y_{min}=2,X_{scl}=1,Y_{scl}=2.$
